Description
An OPC service for providing information about alarms and
events to OPC clients.
An OPC service for providing information about process data to
OPC clients.
Part of a logical node object representing specific information,
e.g., status or measurement. From an object-oriented point of
view a data object is an instance of a class data object. DOs are
normally used as transaction objects; i.e., they are data struc-
tures.
The data set is the content basis for reporting and logging. The
data set contains references to the data and data attribute val-
ues.
A physical device that behaves as its own communication node
in the network, e.g. protection relay.
Change of process data or an OPC internal value. Normally, an
event consists of value, quality and timestamp.
A physical IEC 61850 device that behaves as its own commu-
nication node in the IEC 61850 protocol.
Representation of a group of functions. Each function is defined
as a logical node. A physical device consists of one or several
LDs.
The smallest part of a function that exchanges data. A LN is an
object defined by its data and methods.
A communication protocol developed by Echelon.
A proprietary method of ABB on top of the standard LON pro-
tocol.
Series of standards specifications aiming at open connectivity
in industrial automation and the enterprise systems that support
industry.
Representation of a connection to the data source within the
OPC server. An OPC item is identified by a string <object
path>:<property name>. Associated with each OPC item are
Value, Quality and Time Stamp.
Named data item.
The report control block controls the reporting processes for
event data as they occur. The reporting process continues as
long as the communication is available.
ABB proprietary communication protocol used in substation
automation.
Protection and/or Control Product supporting the SPA protocol
version 2.5 or earlier.
XML-based description language for configurations of electrical
substation IEDs. Defined in IEC 61850 standard.
